Detective: I'm Sato Miwako's Informant

Osamu Shiraishi and Miwako Sato arrived at a rented room on the top floor.

When they arrived, there were already police officers present, and police tape had been put up.

Inside, there's a small bedroom and kitchen combined, with only one separate bathroom. These small houses are very cheap and suitable for working people to rent.

Meanwhile, on the bed in the room, a very young girl was lying there, clearly dead.

Miwako Sato asked the surrounding police officers, "Have you found out who the deceased was?"

A police officer said, "Ms. Matsuda Chika, 21 years old, a university student."

Sato Miwako nodded silently, then looked at Shiraishi Osamu, who was doing nothing.

Shiraishi Xiu flinched slightly and asked warily, "Why are you looking at me like that?"

Sato Miwako said irritably, "I don't want to see this scene today. You examine me and determine the cause of death. And you know how, right? I've seen your experience solving cases."

Shiraishi Xiu wrinkled his nose and pursed his lips, but thinking that he had indeed gone too far last night, he slowly walked up to the corpse.

A policeman readily handed over a flashlight.

Shiraishi Xiu was somewhat surprised, but then he remembered his identity as a detective and understood. He immediately saw the victim's lips with the flashlight and frowned, saying:

"There is erosion on the lips."

"erosion……"

Sato Miwako frowned for a moment, then quickly realized what was going on:

"Mucosal ulceration suggests that this person may have ingested oxidants."

She's been a detective for a long time, so she can identify some simple causes of death just by looking at the symptoms.

"That's it."

Shiraishi Osamu nodded. He had wanted to say something too, but since his future wife wanted to, he could only let her say it.

After saying that, he started searching the room.

The small room was a bit messy, but not in a deliberate way; it was more like a slightly unkempt mess.

It has a mobile phone and a laptop.

Sudden……

Shiraishi Osamu noticed something small next to a small table. He bent down and picked it up. It was a plastic bottle with no sticky notes on it, but it was completely empty.

Before he could speak, a policeman walked over.

Shiraishi Osamu understood and handed the item over to them for safekeeping.

"What did you find?" Miwako Sato leaned closer.

Bai Shixiu shook his head and said, "It's a small bottle, it might contain oxides, we need to take it for testing."

Sato Miwako said, "Alright, let's go together later. We'll have to bring the body over anyway, so we can find out the real cause of death and what kind of oxide it was."

.

Shiraishi Xiu said helplessly, "Can we not go? They'll send us a report anyway."

Miwako Sato said seriously, "This is our job as police officers, not something we do for fun."

"Okay, okay, okay..."

Shiraishi Osamu immediately surrendered, not wanting to argue over such a small matter. After all, he was now a police officer and had to adapt to this work rhythm.

Higashi Sakura Medical University.

The autopsy is performed here, and there is also a dedicated laboratory here.

Osamu Shiraishi and Miwako Sato waited outside the door for the report to be delivered from inside.

"So slow..." Shiraishi Osamu muttered boredly. If it weren't for the security camera above his head, he would have liked to hug Sato Miwako and get close to her.

"If you're bored, you can try to guess what kind of oxide she was poisoned by."

Miwako Sato gave a very good suggestion.

Shiraishi Osamu laughed and said, "Can I hold my wife in my arms?"

Miwako Sato sneered, "I haven't even settled things with you about last night. So, is that what you call 'riding on someone else'?"

After saying that, she couldn't help but blush. It was so embarrassing and so awful.

For her, who has always had a strong, independent woman's demeanor, what happened last night was a disgrace. She was so ashamed and angry that she wished she could take Shiraishi Xiu down with her.

"hey-hey……"

Bai Shixiu smiled, avoiding a direct answer to the question. He was inwardly grateful to his mother-in-law for creating such a space for him. He gently took her hand, ignoring her resistance, and said seriously:

"I think it might be potassium oxide or sodium fluoride. In recent years, sodium fluoride has been the more commonly used industrial product, and the price is different because sodium is cheaper. So I think it's probably sodium oxide."

"Hmph! You think you're so smart!"

Sato Miwako couldn't help but purse her lips, somewhat agreeing with this statement.

With a "click".

The lab door opened, and a woman wearing a mask stepped out, saying:

"The deceased had no obvious external injuries or diseases. The cause of death was potassium sulfide. As for whether it was suicide or forced ingestion of potassium sulfide, that is for you, the police, to determine."

Thank you.

Sato Miwako thanked her profusely.

The woman smiled at the two of them and then went back into Laboratory 340.

Sato Miwako looked at Shiraishi Osamu and couldn't help but smile: "How about that? You guessed wrong, didn't you? You were so smug."

"Shout?" Shiraishi Xiu grumbled unhappily, pulling her outside while saying, "My guess was right. How could an ordinary college student get potassium fluoride? So there must be something serious going on here."

Sato Miwako laughed and said, "Anyway, you just pushed the wrong one."

Shiraishi Xiu retorted, "I already said that I deduced it using normal methods, and this is clearly not a normal thing."

Sato Miwako laughed and said, "Anyway, you were wrong just now."

Shiraishi Osamu: ...

There's something I don't want to say anymore; if I keep going, it feels like an endless cycle of repetition.

They also had to return to the Metropolitan Police Department because the deceased's cell phone and laptop were being hacked, and there might be some new clues.

The most crucial point is that Shiraishi Xiu has already made it very clear that an ordinary college student has virtually no chance of obtaining potassium oxide or similar substances, because it is simply too difficult.

This is why he suspected sodium fluoride, and at the same time, this matter began to reveal something abnormal, developing in another unknown direction.

Chapter 0089: The Winery Organization Behind It

Metropolitan Police Department.

Osamu Shiraishi and Miwako Sato returned here.

As soon as Inspector Megure saw the two of them, he said, "You've come at the right time. A more detailed report on the deceased has been compiled. You can listen to it too!"

Osamu Shiraishi and Miwako Sato sat back down at their desks, waiting for Inspector Megure to continue.

Inspector Megure glanced at his subordinates around him, opened the report in his hand, and slowly said, "According to the report just now, the bottle that Brother Shiraishi found in the room also tested positive for potassium fluoride."

Officer Takagi interjected, "She's a science and engineering student, right? Does she work in a factory? Otherwise, where would she get her hands on potassium enrichment?"

Shiratori Ninzaburo said calmly, "I have the same question."

Inspector Megure looked at the report in his hand and continued, "She majored in literature and worked twice a week at a bakery. Her friends said that she had no suicidal thoughts before her death. No suicide note has been found."

Shiratori Ninzaburo said, "The technical department is already analyzing her laptop and phone, and I believe we'll have an answer soon."

Shiraishi Osamu nodded in satisfaction.

Although I thought the police were trash and incredibly incompetent when watching the anime, when I actually met them, I found that they were quite reliable. They were competent in many things and investigated everything thoroughly.

"besides……"

Inspector Megure's voice suddenly turned serious as he looked at everyone and said, word by word:

"Headquarters takes this matter very seriously because in the past two months, there have been thirteen suicides nationwide caused by potassium oxide."

"Thirteen items!!!"

All the police officers gasped in surprise, their eyes filled with disbelief.

Shiraishi Osamu's brows furrowed deeply. This kind of thing doesn't seem like something that happens often; it's almost like a premeditated and organized operation.

Inspector Megure said sternly, "If this is also a suicide, then it will be the fourteenth case. Let's investigate and see if there are any similarities between this case and the previous dozen or so."

After he finished speaking, he distributed the reports from headquarters to his subordinates one by one.

Looking at the reports and records from the past two months in her hand, Sato Miwako whispered to Shiraishi Osamu, "Osamu, have you noticed anything?"

"Let me finish reading it first." Shiraishi Xiu stared at the report in his hand, turning each page very carefully.

He paused quickly.

I stared at one of the items carefully, and then flipped through the previous reports one by one. I did find some commonalities among them.

"Inspector Megure!"

Shiraishi Osamu shouted loudly, attracting everyone's attention, and then continued:

"I discovered that in the suicide cases over the past two months, some people had their cell phone data or computer data deleted. The only thing they had in common was that they could still communicate remotely and access the internet."

"Online..."

Inspector Megure muttered something to himself, and his spirits immediately lifted.

Just then--

Suddenly, there was a knocking sound at the door.

Soon after, a middle-aged man wearing glasses walked in, carrying a laptop, and said to Inspector Megure: "Excuse me."

"Inspector Megure, the deceased's laptop is now open."

"Really!"

Inspector Megure was delighted and immediately crowded around, followed by the others who also gathered around, staring at the laptop.
